If you’re installing Enzoic for the first time, or even if you’ve had Enzoic installed for a while, you may run into an issue where the keycode comes back as invalid. 

The error message will display as: "Problem validating product key"

There are three main causes for this error. 

  1. The keycode was entered incorrectly: 

  • This is the most common reason users receive an invalid license error when installing Enzoic for the first time. It may seem trivial, but make sure you’ve double-checked that the code you’ve entered is the exact code provided.

  1. The keycode is actually invalid:

  • While rare, it’s possible that the keycode is actually invalid. Either the code has not been activated (for new accounts) or has been deactivated for some reason: i.e. lack of payment, expired subscription, etc. (this will usually affect existing accounts). If you suspect that this might be the reason, feel free to email our sales team at sales@enzoic.com. They should be able to assist in activating the license. 


  1. Enzoic cannot reach the License API: 

  • If you’ve checked that the key is being entered incorrectly and that it’s still valid and active, then there is a good chance that something in your environment is preventing the Enzoic license API from reaching out. 

  • To start, we highly recommend that you go through our installation prerequisites, which can be found here. Even if this is not a new install, all of our prereq’s need to be in place in order for Enzoic to function properly. 

  • Go through our API timeout KB, which can be found here. This covers most of our environmental troubleshooting steps for communication issues.
